Biology and Technology in the Real World: Fracking

What is fracking? Fracking is the process of drilling down into rock face where oil and natural gas deposits are trapped below. Once a suitable depth has been reached, a mixture of sand, water, thickening agents, and chemicals are pumped into the rock to fracture it. This is why the process is called hydraulic fracturing, or fracking for short. Once the rock has been broken, the solution pumped into the fracture creates fissures in the rock where oil and natural gas deposits can theoretically flow more easily, and they can be siphoned and collected. Fracking was…
